We can now read/write the eeprom, as well as the main flash. I think this is about as done as it's going to get. We can read and write across the entire line of Bosch AG5 TCU's quickly and reliably. Big thanks to USBJTAG. Without his interface, and help, this would not have been possible. Anyone interested in giving this a shot should go to their site: usbjtag.com and order an interface  |

Interesting stuff DD. Do you get full access to the MCU with this kit while the processor is running?

good morning,
i came across this thread a few hours before, while searching for OLS816 plugin. I´m very impressed by the results so far and i would like to ask if anyone is able to do checksumm correction on those files?
i´m not directly using the same EGS/TCU, but i´m using the ZF5HP19, too. While yours is front- or 4wd, mine is used in rearwheeldrive, but overall its pretty the same.
The inside of the TCU looks very identical to yours and the files look pretty identical, too. that said, if obvious that the maps are somewhat shifted in position and therefore much difference in winols while comparing.
i´ll attach some files i´ve taken so far and hope they will help others.

We can now read/write via BDM. It requires jumping two pins to shutdown the hardware watchdog, and disabling the software watchdog
Can you show points for WD shutdown on the board photo or using MC68376 CPU pins description ? |

Take a look one page back. You see the wire I added to the BDM? Just pull that high (12v with a 130ohm resistor) and that disables the hardware watchdog.

I've seen the wire and +12V connection point. But it's difficult to determine exactly on this photo what pin on BDM connector is used. Which pin number? |

Pin 7 (reset). You should find that pin 11 is +12v and can be used to pull the reset high.

Searching for the Dump´s
4D0927156AA 3,3tdi
4D0927156EG 6.0 W12
4B0927156FB 4,2T RS6
I want to change the shift rev´s of the W12 and am hopeful to find it with those other dumps, because the transmission of these cars are nearly the same type. If I am sucessfull I´ll post it here.
@ddillenger: I´m interested in your read/write method: If I understand it right you don´t need much more than a good jtag programmer and power supply? Or do I need a appropriate software for the jtag programmer?
I don´t got a good jtag programmer yet, so I would order your suggested tool, but I would like to know if there is something more that is needed?
If someone is interested: I got serveral Dumps of 2,5tdi tcu´s where (imo) torque limiter and shifting time is been adapted (Only 3 values on hexdump), but I dind´t tested so far. I could send ori and mod via pm to those who are active here and are willing to share information here, too...

TNX!
I am very frustrated with myself at this point.  I have my usbbdm hooked to the corresponding pins on the tcu board. I also have a 12v power supply connected and supplied +12v to 55 and 54 -12v is connected to 34 and 35 I have 3 390ohm resistors in parallel and they give me 130ohms. I have this connected to pin 12 (verified +12v) also tried direct to my +12v source. On the other side of the resistor I have pin 7 from the bdm and pin 7 from the tcu tied in. They are seeing roughly 5v. I don't see anywhere in the tread regarding connecting to the K-line is this needed?  It populates info and performs a read but doesn't read anything from the eeprom Code has plenty of info. BDM does stay ON once the reset is sent to it. I am in the process of uploading a video. I have been bugging ddillenger a LOT and I am sure he is tired of my elementary questions. Hopefully this can help someone else in the future. This is on a 2002 audi a8 tcu for reference. -Richard |
